the installation of refrigerant and cooling water;
♦ Factory testing: each refrigerating unit is on load test of not less than
12 hours in the factory.
Structure design
A fully closed piping design, high efficiency plate heat exchanger used to reduce the
demand for the thermal fluid utilization while providing the system to achieve the rapid
ups and downs in temperature.
Display funcation
Displays various information on the touch screen.
Process Control Schematic diagram
High repetative of tempeature control effect
Each cycle curve slope is consistent and greatly improve the consistency of production thermostatically control environment.
